SPINNING AND DANCING TOY.

SPECIFICATION forming part of Letters Patent No. 719,276, dated January 27, 1903.

Application filed March 14, 1902. Serial No. 98,147. [No model.)

To all whom it may concern: point is to bring the center of gravity close Be it known that 1, JOHN S.

The spinbe passed down through the string-receiving ning device consists in a top furnished with bore 8 and laterally through that portion of a disk-shaped body 4. and having on one side bore 9 which is farthest away from the perof said body a short pivot-point 5, formed in son, while the handpiece 10 is held by the left 7 an ogee with said body, and on the other side hand. Then the spindle will be inserted down "mo a long slender taper spindle 6. The purpose into bore 8 and the body lof the top brought of the broad thin disk 4: and the short pivotto rest on the top of the handle; who

tirely unwound from the spindle the spinning body 'or top will become freed from the handle and will spin upon any smooth surface for an extremely-long period of time.

3 spin the toy left-handedthat is to say,

- in order to draw the cord with the left hand ----the.f ee end of the cord will be passed through the portion d of the bore 9 instead of through the portion 0 thereof, as described, or 'if the handpiece 10 is held in the right hand while adjusting the cord the cord then may be passed through the hole (1, (shown in Fig. IL) and then the toy will be inverted, thus bringing the free end of the cord into position to be drawn by the left hand.

In order to give a pleasing variety for the use of the toy, the point of the spindle 6 may be provided with an irregularity, projection, or cam 11, which is arranged at one side of the point of said spindle, and by appropriately adjusting and holding the parts the top may be made to spin upon the spindle in a dancing manner.

' It is not necessary that the cam 11 should be very great, and in the drawings it is exaggerated somewhat for clearness of illustration.

To spin the top in a dancing manner, the cord will be wound on the spindle substantially in the way above described, and for spinningwith right hand the free end of the cord will be brought through the portion (Z of the bore 9 which is next to the person, while the handpiece 10 is held in the left hand, and the operator will cant the handpiece to one side andwill then draw the cord through the hole d, thereby giving the spinning body a high speed of rotation and at the same time drawing the spindle 6 and top-body 4 up, as indicated in Fig. II, and at the latter movement of the cord the handle 1 may be suddenly brought down, thereby freeing the spindle from the handle, whereupon the top will fall to the surface upon which it is to be spun and standing aslant thereon will begin to dance and will continue to dance until the rotation ceases or until the top may attain an upright position;

' If the spindle] f1 were perfectly smooth at the tip and the surface upon which it is spun were also smooth, the toy would spin on the I spindle with a steady and smooth motion.

norder to construct the toy at minimum 23. "cos and in a dlIl uleand superior manner,

the same is formed of two members, as suggested in Figs. III, V, and VI. One of these members e is a block of suitable dimensions for forming the body 4 by turning the same in a lathe.

f is a stem, which originally may be square in cross-section from end to end, but which before assembling the parts will be turned for a space at one end, as indicated at g in said Figs. V and VI. The block a will be perforated by boring a centrally-located hole It therethrough,whereupon glue or some other suitable cement may be applied to the cylindrical portion 9 and the same inserted in the hole h and the glue allowed to set. Then the body thus formed, as shown in Fig. V, may be placed in the lathe and reduced to the form shown in Figs. I, II, III, and IV.

The under part of the block will be turned to form, with the lower end of portion g, the pivot-point 5 at the end of the axis of the stem.

The spindle 6 will be turned to slender taper, and the upper face of the block will preferably be left fiat throughout its main portion, but rounding at the periphery, as shown in Figs. I, III, and IV. It is to be understood, however, that I do not limit myself as to the exact form of the portion 4. The same may be varied without departing from my inven-- tion in its main features. In practical manufacture a single stick (not shown) may be turned at intervals to produce cylindrical portions g, with intermediate unturned portions f, and after thus being turned the stick may be cut in any suitable manner into appropriate lengths for forming the spindles and pivot-points of the tops.

By the construction shown the center of gravity and the axis of the spindle may be made to perfectly coincide. The-pivot-point 5 will. be at the end of such axis, so that there will be no liability to wabble in spinning the top.

The spindle 6 may be made of very hard dense wood and the main body 4: of wood of a less expensive character, and a top of great durability and superior spinning qualities may thus be produced at a minimum cost.

The grain of the stick which forms the spindle runs lengthwise of the spindle, and the grain of the block which forms the main body for the top will have its grain running at right angles to the grain of the spindle.

The top may readily be spun for a considerable time by simply twirling the spindle between the fingers of the hand; but in order to get the most satisfactory results and also I claim as new, and desire to secure by Letters Eatent of the United States, is-
